please find my design submission for your bathroom renovation attached. My goal was to design cosy and elegant bathroom considering space limitations and your wishes. In that regard I designed two vanities and separate bath and shower. Since you said that your husband is tall as the lowest part of the slanted ceiling I designed 48'' wide shower so half of it is standard 80'' high and the other half is under slanted ceiling. In this way shower could be used by both, tall and not so tall users. In my design I have used the Metro Gris tiles which you already have but in order to create more appealing design I also used mosaic tiles with the grey and brown colors on the slanted walls. The grey color on the mosaic tiles is related to the Metro Gris tiles and the brown color is related to the wooden parts of the vanities. I use wood on the vanity to add some „warm“ materials to the grey and „cold“ tile design. I hope you like it!
